Why is FFA slow to act on ACL: Muscat

Melbourne Victory coach Kevin Muscat says it shouldn't have taken Australian football's worst-ever night in Asia for Football Federation Australia to act on A-League scheduling.

The horrendous Asian Champions League results on Tuesday night - Brisbane were battered 6-0 by Ulsan Hyundai and Western Sydney 5-1 by Shanghai SIPG - prompted Roar coach John Aloisi to complain FFA's inflexibility had made it "virtually impossible" for them to compete on the continent.

Both sides played after long flights to Korea and China on a three-day turnaround from A-League games.

The scorelines were labelled by pundits as the "darkest day" in Australian club football, then Adelaide United fell 2-1 to Jiangsu Suning on Wednesday night.

It appeared to galvanise the governing body, who within a day had pledged to give clubs what they've campaigned for the past several years - an A-League draw moulded around the ACL.

"I've been speaking to a couple of others about making sure that we have some flexibility around the ACL draw for next year," A-League boss Greg O'Rourke said on Wednesday.

"The only constraint around that will be venue availability."

O'Rourke said the biggest issues centred on the NRL and AFL using common venues from March, and that A-League fixtures were completed six months before the ACL draw.
